Oddly, I wound up stumbling across this (from the IIsi hardware developer's guide). I'm going to pick up a set of male 13w3 and DA15 connectors from Mouser will-call tomorrow afternoon and give this a test...

I've recently picked up a Portrait Display with no cable, so I have no way to test it. Does anyone know the pinout for the 13w3 connector (found a thread where someone on here had built one, but didn't provide the pinout)? Alternatively, is there anyone on here in the North Texas area that has...

Nice! Glad to see this is still marching along - I'd love to finally be able to replace all my dead or dying SCSI drives.

Alrighty, back with an update! The chassis has been recapped and the two resistors replaced and, lo and behold, it powers up! Except now I have a vertical linearity problem and the screen jumps up and down like a Jack Russell Terrier. Adjusting the V-LIN pot all the way leaves several lines of...

Same here, friend.

Howdy everyone! I've got an SE/30 that I'd like to try to get A/UX running on at some point, but have no desire to spend the exorbitant prices that rare-as-hens-teeth SE/30 PDS network cards command. I do, however, have an Asante EN/SC SCSI ethernet adapter. Out of curiosity, I read through the...

I'm down for a few as well.

I'd bet money on this being a culprit; I've had a few Macs with image geometry/stability issues before and after recapping where it turned out the opto IC was at fault. While this won't solve all of your issues, it is a cheap fix that more than likely will address part of them. My other bet...

Ran into a similar problem a while back; the on-screen pattern was slightly different, but the card was bad.

That first image you posted makes it look like the nipple has broken off the back of the CRT. Is there a hole on the end of that tube where the bent pins are? If so, that tube is toast. Thankfully, they are all pretty interchangeable; you should be able to find a dead compact Mac for cheap that...

The TL866II is what I use and it's pretty dang nice. It also has a TTL logic IC tester built in, which is incredibly useful in troubleshooting 74-series logic chips. It's about $50-60 on Amazon and worth every penny. As dochilli said, you'll want to dump your Plus' ROMs and compare them (the...

Well, that's about the coolest thing I've seen today. Planning on selling blank PCBs soon? Mouser is literally across town from me, so UPS ground gets here next day (I miss the days of same-day will call :( ). I would love to put a few of these together to drop into some stuff.

Second on checking voltages; I'm guessing you tried the original "faulty" expansion card in another Classic as well? I suppose it is entirely possible that the original card is indeed bad, but you also very likely have another underlying issue on the logic board or analog board. But yeah, check...

I'll echo all of these sentiments, and Scuzzino sounds amazingly on-point!

Very interested; depending on the price, I'd be down for several. Heck, I'd be down for several blank PCBs and a BOM at Mouser; I have no issues assembling something like this. I've got several Macs that have dead hard disks and can't exactly afford to drop a SCSI2SD in every one of them.

After working on my IIx to get it up and running, I've been wondering about something. I have a dead, and almost certainly unrepairable, IIfx (there's something screwy going on in the NuBus section, in addition to exploded batteries that I've been fruitlessly repairing damage from) with a 40MHz...

AARGH - RAM! After testing in my Classic, two of the four 1MB SIMMs are bad. The Mac IIx can boot off of 1MB of RAM, so long as it's in the form of four 256K SIMMs in the four seats in bank A. Now that I'm down to two 1MB SIMMs, I need to take something apart to test with other SIMMs. EDIT...

I can take some high res images in a little bit and post them here; a broken trace is my worry, as well. All of the RAM I've tried aside from the SIMMs that came with this thing give me no boot chime or error tones, just slow chimes (as opposed to the boot chime/error tones/fast chimes with the...

Replaced with a working 74F240 to no avail; back to the drawing board.

Too late to edit, but, after flipping through the Dead Mac Scrolls, I came across this:  "On startup, you get the normal startup chime, then you get a high note, followed by an even higher note, followed by a do-do-da-da sound. Then the raster blacks out." My raster doesn't black out, but, that...
